"Riverdale" got a little violent Wednesday night, and it wasn't due to the Black Hood.

Archie and the football team went toe-to-toe with the Southside Serpents on a rainy night, leaving Dilton stabbed in the leg, and Archie bought a gun with some ammo earlier in the day. While all that drama was happening, Jughead and Betty were working to decipher a message left to Betty by the Black Hood.

As always, the show did manage to squeeze in some fun pop culture and comic references, and INSIDER worked with Archie Comics to shed light on some of them.

Here are six details you might have missed from Wednesday's episode of "Riverdale."

1/

Jughead describes Archie as a "milquetoast" when the Southside Serpents talk about going after him.

A "milquetoast" is a timid person, but this isn't the first time we've heard that vocab word used on "Riverdale." On episode nine of season one, Alice Cooper walks into Betty's room when Jughead is present and calls Hal Cooper, Betty's "milquetoast father." This is probably where Jughead learned the word.

2/

Fogarty makes his "Riverdale" debut.

Fogarty is presumably Fangs Fogarty, an Archie comics character from the "Little Archie" comics. The comics followed Archie and his friends as children and Fogarty was the bully.

3/

Toni comes upon Jughead reading books about the Zodiac killer and name drops Robert Graysmith's "Zodiac" and "Zodiac Unmasked" books.

The show has been drawing a lot of comparisons to "Zodiac," so it's fun to dive into the references.

4/

When Archie goes to buy a gun and ammo, he uses a fake ID with the name "Wilbur Wilkins" on it.

Wilbur is actually a character who debuted before Archie Andrews as a character published by MLJ Comics, which later became Archie Comics. Some of his stories were reprinted in various Archie Comics Digests.

5/

Toni Topaz made a joke about Betty's "iconic" ponytail.

Betty always has her hair up.
The CW

Betty Cooper is known for her updo in the comics. When Kevin, Jughead, Toni, and Betty are trying to decipher the Black Hood's code, Toni says maybe Betty could think better "if she loosened her ponytail." The group looks up in surprise and Kevin calls out Betty's normal look.

"Betty's ponytail is iconic and beyond reproach," he says.

Betty does take her hair down after Toni's comment, though.

6/

Other pop culture references in the episode included: "Lord of the Flies," "Nancy Drew," "The Girl With the Dragon Tattoo," and serial killers Ted Bundy and Aileen Wuornos.

Veronica mentions "Lord of the Flies."
The CW

The show throws in a lot of book and movie and true crime references for people to pick up.
